Reply To: impact or crown?
I would stay away from the Dreamline for a bit. While the base model is supposed to be around $1000, it’s fugly. If you like wood or traditional stuff, it’ll run at least $300 or $400 more. That brings it up into the synthetic Crown range. Nice but the extras add up in a hurry and first run products always have some jitters. Let it settle down and get a later model.
As for adjustments, both are incredibly adjustable to achieve target pellet speeds. The Impact has a knob that controls how far the valve opens (from what I understand). The Impact has a control that controls the valve opening. Different, but can both be adjusted to really adjust the speed.
Again, I don’t think either is superior to the other, to me it all comes down to configuration. If you like a bullpup / tactical design, Impact. If you like a traditional rifle look, Crown.
I don’t really care for the bullpup look, but wanted the short gun, therefore, Impact. Other than that, I really don’t see any difference between accuracy, adjustability, or anything else.
